Max for live – no audio?

Sorry in advance for being a pain here, I’ve been searching all day to find a solution but with no luck. I’ve recently started to use max for live and everything is going well, apart from one thing, I get no audio output from m4l. I’ve checked my settings, reinstalled max msp and searched google for answers.
I’ve been following some tutorials to aid me in the device I want to build, an integral piece of this is the ability to store and play back a sample, and all of the tutorials show signal and audio being outputted and even following these tut’s exactly I get nothing. Now because I have more than that going on in max I decided to just set up an simple one with nothing else but I still get nothing back. Example, http://compusition.com/web/tutorials/max/stepler/1 I followed this tutorial, as well as others but I’m left wondering why nothing is working. Is there something I have overlooked possibly? Or a known issue perhaps?
In regards to setting up max for live. It’s version 5.1.9, I’m on mac os mountain lion late 2011 macbook pro if that helps.
Apologies for the rookie question that will most likely leave me kicking myself when someone tells me the answer :)

Hi yes it was an audio/instrument device but I figured out the problem and it was a definite schoolboy error :/
I had been following some max msp tutorials to get to grips with some features and terms but of course max msp is a little different to M4L in the sense that they do not have ‘plugout’ – so I couldn’t see where I was going wrong.
I’ve just redone a simple patch with an SFplay going into a live meter then to ‘plugout’ and I’m getting sound now. Excuse my schoolboy error :)

Ok so the meter on the left means that MIDI data is definitely going in but there are a whole host of things that could have gone wrong from that point. Could you post your patch for us to have a look at it would be much easier to diagnose the problem then. Just to clarify there’s absolutely notion happening on the meters on the right side of the device?

Apologies for the noobishness but I think I’m having a similar problem. I’ve been following the tutorials in the "Max/MSP/Jitter for Music" book but am having trouble with some stuff I’ve been building in Max for Live. I’m using my computer keyboard as a MIDI controller and Max for Live as an audio effect. I have been following tutorials to build a MIDI looper, but the patch does not seem to work (i.e. it doesn’t record or playback the phrases I play).

I reckon it’s a really basic and obvious error that anybody with even a cursory knowledge of Max should be able to help me with. I’ve attached a picture of the patch in question, and any help given here would be greatly appreciated. Thanks!
